Although planets surround stars in the galaxy, how they form remains a subject of debate. Despite the wealth of worlds in our own solar system, scientists still aren't certain how planets are built. Currently, two theories are duking it out for the role of champion.
The first and most widely accepted, core accretion, works well with the formation of the terrestrial planets but has problems with giant planets such as Uranus. The second, the disk instability method, may account for the creation of giant planets.
"What separates the ice giants from the gas giants is their formation history: during core growth, the former never exceeded [critical mass] in a full gas disk," wrote researchers Renata Frelikh and Ruth Murray-Clay in a research paper. The core accretion model
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
With the rise of the sun, the remaining material began to clump together. Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium, from the closer regions, leaving only heavy, rocky materials to create terrestrial worlds. But farther away, the solar winds had less impact on lighter elements, allowing them to coalesce into gas giants such as Uranus. In this way, asteroids, comets, planets, and moons were created.

[[How Did Uranus Form?]]
A anus-deficient skink Crawling along the ground had a stick fall on it causing an indent, then over millions of years, this indent turned into a hole and somehow intestines formed going from anus to throat, and thus was born the anus and digestive tract- for which the skink was eternally grateful being that it could not poo for millions of years
How Did Uranus Form?
They took a casting of James Carville.
When a daddy and mommy love each other very very much.....
I'm pretty sure you win the interwebs!
>>Who wants to know?<<
All the guys at Man’s Country.

Thought that’s how the dung beetle came to be.
Lol! The Kenyan president and his ‘come hither’ look.
Did you REALLY think you were going to post this title and come out unscathed?
We need a new name for this planet to remove it from the joke category. Maybe Herschel after its discoverer? Or find some other Greek god, they had a bunch.
Uranus is actually quite an interesting planet. It rolls along sideways with its poles pointing almost in the orbital plane. No other planet is nearly so inclined to its orbit, I think Mars beats Earth by about 1 degree. Jupiter and Saturn are closer to being perfectly upright in their axial tilt to the orbital plane.
It also wins a rather odd award for having the smallest set of satellites of the four gas giants, by quite a large margin, and even the Earth has a bigger one (see how this gets derailed by the name?).
“How Did Uranus Form?”
God ripped that part of the solar system a new a-hole?
I’ll show myself out.
Isn’t URANUS where Liberals are conceived under rocks?? Then they slither out.
Oh, and did I mention I wear a size 18 ring and can palm a basketball???
Beat me to it. :P
Sphincter says what?
why are they called hemorrhoids and not asteroids?
Gustave Holst’s ‘The Planets’ has seven movements. Does not include the earth. Surprisingly, the inspiration was not fully derived from astronomy. The Planets was based on an interpretation of the astrological essence of each planet in the solar system as known at that time. Uranus was characterized as
“Uranus, the Magician”; boisterous, powerful and icy.
Not for a moment.
